想請教下咁多位MF對焦點用??
MF 同 AF分別係邊呢??
見好多靚鏡只設MF又何解....???

MF即係手動對焦，同AF的分別係，一個手動，一個自動囉。

That's make them look professional. Leica rangefinder camera is using manual. Just kidding.

In some situations, the AF is fooled or unable to focus. Then you need to use manual focus. Most of the time people use manual focus to take macro pictures.
